@Supreme Marvel: You mean nigh-omnipotence with the Choushin, right? Considering the three were questioning the existence of a power greater than their own, they wouldn't be considered omnipotent if there is someone greater than them.

@Veiler:

1. It's never explained that he's omnipotent in the show or in an author interview.

He was. Kami Tenchi was aware of events yet to come with Tenchi and was apparently great enough where the Choushin had to use differing means that they thought would trigger his existence coming to being. He was one of the few things in the series that the Choushin had no easy means of fully comprehending.

2. He doesn't have any good feats.

He was able to calm down and wipe out the Counter-actor rather easily as the Choushin couldn't take her out due to her status as a counter-balance to their influence on existence. I'd say that is an impressive enough feat on top of knowing of things yet to come and being one of the few things in existence that the Choushin weren't fully aware of.

@Supreme Marvel: You mean nigh-omnipotence with the Choushin, right? Considering the three were questioning the existence of a power greater than their own, they wouldn't be considered omnipotent if there is someone greater than them. .

They wanted to create a being beyond their omniscience, by creating anomalies across the multiverse. Which created Z and Tench; who had more potential.

@Supreme Marvel: Not quite. At some point after the Choushin created the Tenchi multiverse, they became aware of the possibility that there was a being far greater than them in power that existed. So to bring out this higher being, each of the Choushin devised different means in which to draw out the being, Tokimi's means being the creation of different anomalies throughout the multiverse which led to Z gaining the Light Hawk Wings. Tsunami created the Juraian Empire to create a superior race that could eventually lead to the birth of the higher being in a human form. Washu gave up her powers and memories as a Choushin sealed in three gems to become human so she could start fresh with knowledge and eventually encounter knowledge that leads her to know of facts concerning the higher being's existence.

@Dream: That's not proof. In fact it has nothing to do with what you're replying to. I want a direct screen cap from the anime with subs explaining that he's omnipotent, not some fanboy excuse based off of fallacies and flawed reasoning.

@Veiler: Not quite flawed or based on personal bias. Kami Tenchi was sought out by a trio of goddesses who created the very multiverse and have knowledge of all its various properties, except for Kami Tenchi's very existence which contradicted the omnipotence they believed themselves to have. Not to mention much like TOAA being an Author Avatar of Marvel Comics founder Stan Lee, Tenchi/ Kami Tenchi is implied to be Tenchi Muyo series creator Masaki Kajishima putting himself in his own series to satisfy his personal harem fantasies. Also unlike most anime/ manga franchises, Kajishima is known to also write up novels and doujinshi that expand upon characters and elements to the world of the Tenchi franchise. There is a well-known Tenchi site I'm familiar with that provides plenty of answers to common questions regarding both the storyline and behind the scenes elements to the Tenchi franchise called Tenchi Muyo! FAQ which is one of the best sources for Tenchi info I've come across online. Here are some answers to questions regarding the matter of Tenchi's status and the purpose of the Choushin:

What's
the Third OAV going to be about?

This
is a summary of what was revealed in the Kajishima-sensei interview: Much of the OAV is
going to consist of the "Choushin Contest," some sort of contest
between Tsunami, Washu, and their sister, the mysterious Tokimi-sama. A new
character named "Z" will be introduced. "Z" is a servant of
Tokimi-sama's and will have to fight Tenchi.

Wait!
Choushin War is how it was translated in the interview. Why are you
calling it Choushin Contest?

Because
"Choushin War" was a mistranslation. The three Choushin were in
a contest to find a kami (god) higher then themselves and they
set about to find this in their own unique ways. Tenchi was what they
were looking for. As such, there was never a war between the three
sisters.

Tenchi
is a kami?

Yep.
That is why he was not only able to generate his own Light Hawk Wings, but do
material conversions with them.

I'm
still not 100% clear on the Choushin's Purpose. Can you explain?

Sure.
The Choushin are high-level entities who created the 3rd-dimension and other
dimensions as well. However, at some point they became aware of the
possibility of a higher-level entity than themselves -- a kami. As Zero
couldn't prove the existence of Tokimi-sama when she saw her, the Choushin
couldn't prove such an existence, nor could they create such a person. So
for a very long time, they did things to try to see if this kami existed or
not.

Eventually,
the three sisters came upon a new plan of attack. Washu placed her
Choushin powers and conscious into three gem-balls, then created an infant
human body for herself in the 3rd dimension. She had no memories of
anything prior to being left at the monastery and she then set out to learn
everything that could be learned from scratch. With this approach, she
hoped to find the kami.

Tsunami
came to the 3rd dimension as well. Using her own existence, she attempted
to create a new type of life -- the Royal Trees on Jurai. However, with
the man who would become the first Emperor of Jurai, Tsunami saw potential that
a superior life form would be born from them. Thus, she swore to protect
him and his descendants while she waited for the birth of Sasami (whom she was
destined to merge with) and Tenchi, who is the kami they sought.

Tokimi-sama
followed the original plan and distorted the harmony they had created in the
multi-verse (the multiple dimensions of the universe). She did this to
cause anomalies from which she hoped the kami would emerge. Z was the
result of her actions and Tokimi took him as he was the greatest potential
she'd found.

The
Choushin considered (past tense) Tenchi to be another potential (albeit the
best one yet, due to his material conversion ability), but Tsunami and Washu
decided that they cared more about Tenchi as a person than whether or not he
was that superior hyper-dimensional being. That is why Tsunami interfered and
Washu said that she wanted to leave it up to Tenchi. After Tenchi killed Z, it
became apparent that Tenchi was indeed that being that the Choushin were
looking for. That is why Tokimi became ecstatic and Noike began to cry happily.

However,
as Tsunami and Washu stated, finding out should be fun and not rushed,
therefore they will continue their lives on Earth with Tenchi. Whether
Tokimi joins them or not remains to be seen.

@Dream: Once again, there's nothing about omnipotence there. And there's no explanation that implies omnipotence, and the word itself is never used. In fact his powers aren't explained at all beyond that he can convert matter to energy with light hawk wings.

@Veiler: Then I don't know what else to tell you considering you seem seem to very strongly oppose the idea. It's become accepted by many folks online that Kami Tenchi is Tenchi Muyo's resident omnipotent unless Masaki Kajishima steps in to expand his title's plot and reveal a character stronger than Kami Tenchi. All that I can say is that any fictional title with an omnipotent is quite vague in giving feats for said characters other than giving just enough evidence to show that said character is above all other cosmic beings, nigh-omnipotents and multiversals like TOAA (Marvel Comics), the Presence (DC Comics), Lord of Nightmares (Slayers) and Man of Miracles (Image Comics).

Now, you can pretend that Kami Tenchi is omnipotent all you want. I don't care about that. But if you can't point out an instance where his powers have been explained to be without any conceivable limits, or that he's explicitly been referred to as omnipotent, then there's no reason for me to accept it.

@TheBlackDragonz: @Dream: No, there's no proof that he is. Read through Dream's "evidence" and see for yourself, this is all there is. But if fanboys will believe that Madara from Naruto is omnipotent, then I don't see why people wouldn't believe that Kami Tenchi is omnipotent.
